According to my tests, isset() is 4 times faster than property_exists(), so use a combination of
these functions in your programming for best performance.
For example:
<?php
$fld = 'somevar';
if (isset($this->$fld) || property_exists($this, $fld)) {
}
?>
If your programming routinely checks a larger number of property names that are expected to exist,
whereas a smaller number may not, then using isset(), as above, will result in faster execution of
the programming.
